>>29160647Alchemy and spiritualism have many "wheels" so it's hard to say what exactly it could relate to.
I think the chakras (chackra = wheel) are important in this case somehow.
We can also look at the galaxy and its center, and maybe the earth's core too, as spinning wheels, much like the chackras in our subtle bodies.
Of the 7 most well known chackras, the most important one is the Heart Chackra, because that's the one through which our body can spiritualy connect to both the Earth Star and the Soul Star, in other words, the Earth and the Universe or Galactic Center.
I also think that's why the first Platonic Solid mythical to be introduced was Diancie, because she's the Octahedron, which is the Solid connected to that Chackra and that diamond shape we can project around us that would theoretically allow us to travel around everywhere.
Moreover, the Diancie movie was all about in believing in yourself and your connection to others, in other words, love. If you pay attention to the lyrics of the ending song you will see that's the message they want to get accross since then.
Maybe that's what they mean, that you have to visit you inner self to find the answer. Maybe it's to learn to love or something similar, don't know.
In certain alchemic writings I could find, it seems like Vulcan is seen as this perfect personification of the alchemist, which gathers the 7 colors of the rainbow in a pure white light. Therefore it could possibly be connected to Platinum, once called White Gold, and maybe that Soul Star pokémon we are thinking about here.
